The prophet peace be upon him said: he who stands (praying at night) reciting 10 verses (from the Quran) will not be written amongst those who are forgetful (of Allah) and he who stands up (at night) reciting 100 verses (from the Quran) will be written amongst the ‘Qaneteein’ (those obedient with sincere devotion in worship to Allah) and he who stands (praying at night) with 1000 verses (from the Quran) will be written amongst the people who have Qentars (large measuring unit 1 Qintar = 256 Kgs) (in Jennah)
